CAR-HEATER.

Specification of Letters Patent.

Patented Aug. 1, 1905.

Application filed March 10, 1904. Serial No. 197,504-

To all whom it may concern:

Be it known that I, EDWARD E. GOLD, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Im rovements in Car-Heaters, of which the fo lowing is a specification.

My invention aims to provide certain improvements in car-heaters and which are applicable specially though not exclusively to the heating of cars by the circulation of hot liquid, (ordinarily water.) in eneral use.

ccording to my present invention certain improvements are provided in the stove for heating the water and in the adjacent pol.- tions of the system, whereby the efficiency and especially the safety of the apparatus are increased.

It is generally recognized that cast-iron stoves in railway-cars or even in trolley-cars are dangerous, because in case of collision they are very apt to be upset and broken, causing the burning of the car. The brittleness of a cast-iron stove is its principal point of weakness. In the present heater the danger from this cause is removed by Such systems are placing the cast-iron stove in a strong sheetmetal (preferably steel) box, which even if it be smashed and crushed in thecollision will yet hold in the coals and the entire cast-iron stove, even if the latter is broken in pieces. A similar casing of steel is preferablyprovided around the smoke-stack and adjacent parts. The steel box and casing referred to are preferably arranged to utilize the heating-surfaces of the stove and the pipe sov as to obtain a maximum efficiencyfrom the entire system. The box is also preferably arranged to facilitate access to the stove for filling it or for removing the ashes without inconvenience to the passengers. Various other advantages are referred to in detail hereinafter, and the novel features are expressed in the claims.

The accompanying drawings illustrate an embodiment of the invention.

Figure 1 is a vertical section showing the Stovepipe and outgoing circulatingpipe in elevation. Fig. 2 is a section on the line 2 2 of Fig. 1, omitting the seat. Fig. 3 is a view taken at right angles to Fig. 1, partly in section and partly in elevation. Fig. 4 is a horizontal section taken on" the line 4 4 of Fig. 2.

Referring to the embodiment of the invention illustrated in the drawings, A is a stove arranged, say, at the middle of one of the longitudinal sides of a car having cross-seats, as shown. The stove, however, may be arranged in any other suitable part of the car and may be used as well with cars having longitudinal seats as with those having crossseats. It takes up very little space in the car,

only the Stovepipe and surrounding casing interfering with the seating-space.

B is the stovepi e extending out through a hole in the roof 0 the car.

The circulating system may be arranged in any suitable style. For example, it may be as described in my Patent No. 566,904, of September 1, 1896, with a tank upon the roof of the car in communication with the pipe C, the hot water from the stove goin out by way of pipe D and thence through t e accelerator E into the pipe F, which runs around the car according to any desired system and ends in a section G, Figs. 3 and 4, returning ,-to the water-space in the stove. The stove A is formed with a double wall H J, Fig. 4, and the space between the two walls carries the water to be heated. The outer wall J of the stove is preferably provided with anumber of openings for the discharge and return of the water. For example, there may be two holes K in the top, one of which is closed by a plug L and the other of which is used for the outgoing pi e, and there may also be three additional ho es K at the upper portion of the sides of the stove for outgoing pipes, all of which are closed by plugs in the present arrangement, and there may be two holes M near the bottom of the side of the stove, one

of which is closed bya plug L, while the other is connected to the ingoing pipe G. The purpose of these numerous points of connection is to permit of the use of several separate circulating systems heated from the same stove, this arrangement being sometimes preferred.

The double-walled stove is connected by a flange around its lower end with an ash-pit N, which by means of legs 0 is firmly connected to the base P of a sheet-metal box. This box comprises the base P and a cylindrical shell Q, constituting the sides. A top plate R for the box is mounted rigidly a short space below the top flooring of the car. The sheetsteel box comprising the base P and body or shell Q is attached to the plate R and is preferably held together by means of a number of rods or long bolts S and T. The bolts S, it will be noticed, lie just within the shell Q, so as to preserve its proper concentric position with the base P, and the bolts T engage the outer contour of the stove, so as to hold the latter also in its proper position in the steel box. The construction thus provided is extremely simple and efficient. The parts may be quickly assembled or disassembled and are all held strongly in their proper relative positions by material which may be bent, but which will not ordinarily be broken even if the car is wrecked.

In spite of the circulation of water between the two walls of the stove there will be a certain quantity of heat radiated outward from the stove, and I propose to utilize this radiation for heating the surrounding air and to convey such heated air into the car. An air-space is also provided above the top of the stove by arranging the plate R somewhat below the floor-plate U. The steel box has a door V near its lower edge, through which are air-openings and a shutter of the style common in stove-doors. The air passes in regulated volume through the door V, circulates under and around and above the stove, and then passes up into the car, the plates R and U being also provided with perforations, as shown.

The stove is fed from inside the car through a passage W in the floor normally closed by a cover X. In order to avoid carrying ashes through the car, the stove is emptied directly outside. For this purpose the horizontallyswinging door V of the steel box is provided.

This door being opened access is had to the usual means for shaking down the fire and the ash-box may be withdrawn and dumped. Thus besides saving space in the car the present arrangement is clean and permits of a gory quick replenishing of the coal or other The stovepipe is also well protected by being inclosed in a steel box or casing having double walls Y and Z. The prime purpose of the doubling of the wall is to provide a nonconducting air-space between and prevent the casing from becoming too hot to be touched. The casing at the same time incloses the outgoing hot-water pipe D. The casing has a closed upper end, and apertures are provided near the bottom through which the cold air near the floor of the car passes into the casing and is warmed by the stovepipe and the hot-water pipes D and F, and similar apertures are provided near the upper end of the casing through which the warm air passes out into the car. The casing Y Z at its back is spaced a slight distance away from the framing of the car in order to avoid overheating or charring of the latter.

, The particular style of stove illustrated is specially designed for use with the other elements of the combination; but it isobvious that heaters of almost any other type might be substituted for the stove shown. The surrounding sheet-metal box and air-space are of special value where the heater is carried on the outside of the car, as is substantially the case here, in preventing the exposure of the heater directly to the cold and the Wind caused by the movement of the car.

Though I have described with great particularity of detail one embodiment of my invention, yet it is not to be understood that the invention is limited to the particular embodiment disclosed. Various modifications thereof in detail and in the arrangement and combination of the parts may be made by those skilled in the art without departure from the invention.
